Basic Cataract Surgery
Basic cataract surgery involves the removal of the natural lens, replacing it with a single focus intra-ocular lens (IOL). This will allow the patient to see well with the use of glasses.
LRIs and Toric Lens Implants
Astigmatism is caused from the cornea being asymmetrical, or being more oblong than spherical in shape, resulting in blurry vision. When astigmatism is present following cataract surgery, patients will need to wear corrective lenses to see well at all distances. In order to reduce the need for glasses after surgery, astigmatism correction can be performed at the time of cataract surgery.
For patients that have mild corneal astigmatism, the surgeon may perform a limbal relaxing incision (LRI). This procedure involves the surgeon using a femtosecond laser to create a micro incision in the cornea, helping to alleviate some of the corneal tension that causes the astigmatism.
For patients with moderate to severe astigmatism, the surgeon might use a toric lens implant to correct the astigmatism. The special design of the toric lens implant makes it possible to reduce or neutralize the corneal astigmatism during cataract surgery. This lens is designed specifically for cataract patients who have astigmatism and usually results in clear distance vision. Reading glasses will still be needed for near and intermediate distances.
Both limbal relaxing incisions (LRI) and toric lens implants are considered to be elective upgrades and are not covered by medical insurance. During your cataract examination, your surgeon will help you determine if these options are right for your unique vision.
Premium Lens Implants For Cataract Surgery
For those wishing to further reduce or eliminate the need for glasses after cataract surgery, premium lens implants might be a good option. Premium lens implants combine the benefits of basic cataract surgery, astigmatism correction, and add the ability to see up close and at a distance without glasses. Premium lens implants are the only option that allow both distance and near vision in each eye without glasses.
Premium lenses are considered to be elective upgrades and are not covered by medical insurance. During your cataract examination, your surgeon will help you determine if premium lenses are a good fit for your unique vision and lifestyle goals.
